REACTION TOY ARRANGEMENT AND METHOD This is a division of copending application Ser. No. 504,300, filed Oct. 24, 1965, now U.S. Pat. No. 3 ,550,3 1 3.

This invention relates to a reaction toy arrangement and method, and more particularly to a fluid expulsion type reaction motor missile arrangement.

It is a feature of the invention to provide a fluid pressure-responsively connected missile in which the fluid pressure is applied through a pressurizing valve spaced from the fluid-pressure-responsive connection, and preferably self-closing.

Still a further feature is the provision of a multistagetoy interconnection arrangement in which the various stages are hermetically sealed from one another.

Another feature is the provision of afluid explusion reaction motor toy missile arrangement which incorporates a pressure-responsive liquid ejection launcher with provision for spray dispersal of discharged liquid for visually simulating conventional full-size combustion reaction motor rockets.

A further feature is the provision of an improved method of connecting and pressurizing multiple sequential unit missile arrangements.

FIG. 9 is a fragmentary longitudinal section view of a further connector-seal arrangement modification.

Referring now to the Figures of the drawings, in FIG. 1 is shown a multistage rocket toy 10 which in the present embodiment incorporates three stages, although it will become apparent that with the present invention the number of stages is virtually unlimited within the propulsion capabilities of the given rocket size. The illustrative rocket 10 includes three selfseparable stages 1 l, 21, 31 the lowermost or first stage 11 being releasably mounted on a launching pad 41 having a remote control pressure release launch-control valve 53 connected thereto through a hollow conduit 5 1.

Each separable stage or section 11,21 and 31 includes a cylindrical body having a pressurizable liquid storage chamber 14,24 and 34 respectively, enclosed by an annular side wall 13,23,33 respectively, and front and rear end walls 15,16; 25,26; and 35,36, respectively. Stabilizing fins 19,29,39 are formed or secured on the outer surface of the respective stage sections 1 1,21

and 31, and the final or upper stage 31 has a tapered or ogive shaped end 36 for decrease of air resistance during flight.

The forward end walls 16 and 26 of the first and second or penultimate stage sections 11 and 21 have a pressure-sensitive laterally flexible diaphragm wall male connector-seal in the illustrative form of a bulbous flexible nose protrusion 17,27, respectively, which is as a function of pressure in the respective liquid storage chamber 14,24, pressurizable for rigidizing thereof and depressurizable for ease of flexing and discharge thereof from a respective female connection 25a, 25b, 25c; and 35a, 35b, 35c in the adjoining next forward stage 21 and 31 respectively. Each bulbous nose protrusion 17,27 includes a unitary relatively thinwalled integral diaphragm-like body structure having an intermediate enlarged annulus portion disposed between a smaller tip protrusion and a smaller annular portion adjacent the root end. The bulbous nose protrusions serve as pressure-responsive connector seals which lockingly engage and seal the respective female connecting and fluid discharge or expulsion openings 25 a, 25b, 25c; and 35a, 35b, 350. In the illustrative embodiment, each female connecting and fluid discharge or expulsion opening includes an intermediate annular groove portion 25a, 35a disposed between a relatively smaller diameter liquid discharge metering orifice 25b, 35b and a reduced diameter smoothly rounded rim portion 25c, 350. The flexible bulb connector-seals 17,27 are preferably shaped to be generally complementary to the respective mating female openings, although it will be appreciated that differences in shape and size may be accommodated to a degree dependent upon the elasticity of the material forming the bulb-connector seals, in which event when the seal integrity and connection strength are effectively maintained the effective pressurized joint is therefore formed of effectively substantially complementary relation. Some degree of pressure-responsive distension is present in all materials, and the extent of distension employed, if any, will depend upon the extent of manufacturing or design mismating and the elastic distension capabilities of the material forming the bulb protrusions.

As used herein, the term bulbous" or bulb as applied to pressurizable laterally flexible wall connector elements 17, 27, etc., is used in both the specific shape sense of a male shaped connector having an enlarged mid-section, and the generic action sense of a male shaped connector member generally which is capable of lateral swelling, and in each instance having an internal pressure responsive laterally flexible wall section which is pressurizable when in place within a fluid discharge orifice to afford pressure responsively releasable holding action therewith. The fluid-pressureresponsive laterally flexible diaphragm wall connector elements or members 17,27, etc., may, of course, be formed with other configurations and constructions than the illustrated and preferred bulbous configurations and constructions.

Launching pad 41 is pressure-responsively connected to the female connecting and fluid discharge openingslSa, 15b, 15c of the first stage section 11 through the medium of a flexible bulb connector-seal 47 similar to interstage flexible bulb connector-seals 17 and 27.

Although the pressurizing of the various chambers 14, 24, 34 and 45 will tend to properly seat the pre-inserted bulb connector-seals in their respective female openings it may be advantageous and desirable in some instances, particularly in the case of highly flexible bulb connector-seal embodiments to employ a connector bulb insertion aid 71 which may take the form of a rod 73 having a handle 75. The rod 71 may be inserted through the female fluid discharge opening b, b of a particular rocket section to push on and effect manipulation of the respective bulb connection-seal 17 or 27 into its corresponding adjoining next stage complementary female opening 25a, 25b, 250 or a, 35b, 350 as the case may be. To enable use of insertion aid 71 with the interconnection between launcher pad 41 and the first stage section 1 1, the bottom wall 44 of pad 41 may be provided with a central removable plug 49 aligned with bulb connector-seal 47. Plug 49 may be formed with a double tapered nodule detent 49a for ease of insertion and removal and a recessed flat head 49b.

The rocket stage sections 11, 21 and 31 and a launching pad 41 are each providing with a self-closing valve opening 13a, 23a, 33a and 43a, respectively, to enable pressurizing of the respective chambers 14, 24, 34 and 45, after assembly of respective adjoining stages, although the launch pad chamber 45 may if desired be pressurized through valve 53 and conduit 51. Each of the self-closing valves includes pressureresponsive self-obturating inner closure lips 13b, 23b, 33b, and 43b respectively and a flared outer guide opening as indicated at 13c may also be provided if desired. For purposes of illustration of differing locations for the valves, each of the valves 13a, 23a, 33a is shown at a different location on its respective rocket stage section, although it will be appreciated that for a given assembly all valve openings 13a, 23a and 33a would normally lie in the same general position on the respective different stage sections. A conventional valve needle 61 of the type commonly employed for inflating footballs, basketballs, etc., and a conventional air pump (not shown) may be used in conjunction with valve openings 13a, 23a, 33a, and 43a to effect pressurizing of the respective chambers 14, 24, 34 and 45.

It will be appreciated that inasmuch as the illustrated first and second stages 11 and 21 are interchangeable, it is a simple matter to reduce the number of stages to two or one by elimination of one or both of stages 11 and 21, and to increase the number of stages as desired by adding additional stages identical to either stage 11 or 2 1.

As an example of assembly and launching of the rocket 10, water is added to partially fill first stage storage chamber 14 as by pouring into the effective funnel-mouthed opening 15a, 15b, 150 while the section 11 is inverted, and launching pad 41 is thereupon mated with section 11. While retaining the assembly 11, 41 in inverted position, the chamber 45 is pressurized through valve opening 430 or through line 51 to effect secure retaining connection and sealing of the launching pad 41 to the first stage 1 1 through pressureresponsive bulb and socket connection 47, 15a, 15b, 15c. Thereupon, water is added to partially fill storage chamber 24 in second stage section 21 while holding the second stage in inverted position, and the first stage bulb connector-seal is then inserted into the opening 25a, 25b, 25c, after which the first stage chamber 14 is pressurized through valve opening 13a to lock sections 21 to first stage section 1 1 and the assembly 11,41. This same operation is then repeated for partial filling of third stage section 31, connection thereof to second stage section 21, and subsequent pressurizing or second stage 21 through valve opening 23a to lock sections 21 and 31 together. The assembly operation is then completed by pressurizing final stage chamber 34 through valve opening 33a, and the assembly is then ready for launch.

The foregoing method of assembly is most advantageous when the bulb connector-seals 17 et al. are of sufficient rigidity to enable flexing insertion without the aid of tool 71, as only two pieces need be held together at a time in unsecured connected condition. However when it is necessary or desired to employ the insertion aid tool 71 on all interstage connections, a different assembly procedure may be employed. In this instance the final stage section 31 is first partially filled with water while inverted and thereupon the second stage section 21 is connected thereto by inserting the bulb connector-seal 27 into the opening 35a, 35b, 350, using the tool 71 through second stage opening 25a, 25b, 250 to aid in this assembly. Water is then added through opening 25a, 25b, 25c, to partially fill second stage 21, and first stage 11 is connected to stage 21 through insertion of bulb connector-seal 17 into opening 25a, 25b, 25c, using tool 71 through opening 15a, 15b, 150. Water is then added to partially fill the storage chamber 14 of the first stage 11 while continuing to hold the assembly 11, 21, 31 in inverted vertical position, and the launch pad 41 is then connected by removing the plug 49 and manipulating the tool through opening 46 to aid in positioning the bulb connector-seal within the mating connecting and fluid discharge opening 15a, 15b, 15c of the first stage section 11. Plug 49 is then replaced, and thereupon launching pad chamber 44 is pressurized through either valve opening 43 or conduit 51 and valve 53. This secures first stage 11 and launch pad 41 together in sealed relation and chamber 14 is thereupon pressurized through valve opening 13a to secure stages 11 and 21 together, whereupon second stage 21 is then pressurized through valve opening 23a to lock and seal stages 21 and 31 together, and final stage chamber 34 is then pressurized through valve opening 330 to ready the assembly for launching. It will be appreciated that in this last described method of assembly a holding jig or fixture may be used if desired to retain the various sections in position during assembly, although such may be accomplished by hand only if desired, particularly with the aid of a second person.

To launch the rocket 11 from the launch pad 41, the assembly 41, 11, 21, 31 is turned to a vertically upright position as shown in FIG. 1, and valve 53 is released to release the pressure within chamber 45. The pressure within chamber 14 of first stage 11 will then cause the flexible bulb connector-seal to laterally collapse and be ejected from the opening 15a, 15b, 15c and liftofi will occur with the subsequent continuing discharge of liquid through metering orifice 15b. The rocket assembly will continue upward under the reaction force influence of the ejected water mass from orifice 15b until the pressure in chamber 14 drops sufficiently to enable the then greater pressure within chamber 24 (which was initiallyapproximately similar to that of adjacent chambers 14 and 34), to overcome the holdingv action of bulb connector-seal 27 in opening 25a, 25b, 25c. Upon reaching this pressure difference the second and third section assembly will then separate from the first stage in a manner similar to that of first stage 11 and launch pad 41. The second and third stage assembly 21, 31 will continue upward together until a similar pressure differential separation occurs between these two stages, and the third stage will thereupon continue upward alone under its own reaction motor thrust power through liquid ejection from metering orifice 35b. Upon exhaustion of the liquid from each of the stages the thrust will quickly drop to zero and the stage will thereafter drop to the launch area. Upon recovery of all stages the rocket 1 1 may be reassembled together with launch pad 41 and launched again.

For ease of manufacturing the various stages and the launcher may take various forms. For instance, as shown in FIG. 2, illustrating a modified construction of rocket stage section 111, the body 111 may be formed in several pieces which are then suitably bonded together to form the unitary body. In this modified embodiment the rear end wall is formed separately from the side and forward wall section 113, 116, as is the self-sealing valve 118 and the bulb connector-seal 117. The rear end wall is formed as two or more split laterally mating sections 115, 115", each having a concave-concave intermediate groove surface 115a, small diameter concavo-convex metering orifice surface l15b and reduced diameter neck rim surface l15c. With this construction the separately formed pieces may be formed of different materials consistent with their required function. For instance, the bulb connector-seal 117 may be formed of softer more elastic material than body 113, as may self-sealing valve 118. Bulb connector-seal 118 is secured to the main body 113 through bonding of an intermediate neck portion 1170 and flange retaining portion 117d to the adjoining area surrounding opening 116 in end wall 116. Valve 118, which is preferably of soft pliant rubber, is inserted through an opening in side wall 113 and is bonded thereto and/or held in place by tight friction fit which aids in assuring self-sealing of the opening 1 18a. In addition it may be noted that each of the valve openings 1184, 180, etc., of the various valves may be formed by puncturing with a sharp small diameter needle, or by other conventionally practiced self-closing valve construction techniques. Further, various other valve constructions may be employed for the valves 118, 18a, etc., as desired, it being desirable however that the valves be self-closing in the discharge direction.

FIG. 3 illustrates a modified launch pad arrangement which provides added simulated realism to the launching operation. In this modified embodiment the housing 243 for the pressurizable fluid chamber 245 of the launch pad 241 has radially extending liquid discharge orifices 244 formed at circumferentially spaced positions about the annular periphery thereof. The orifices 244 preferably have a flared inner seat end and are releasably closed by substantially complementary pressure releasable plugs 242, each having a double tapered retention nodule end 2420 seating on seat 2440. The plugs 242 are preferably additionally connected for safety and retention purposes to the launch pad 241 through the medium of a flexible cord or other flexible line 281 secured through spaced eyes 257 formed in the annular outer upstanding rim 253.

The launch pad 241 may be secured to the ground for stability, if desired, as with anchor pins 283 extending through the base 251 thereof. While not shown, a tool receiving opening and a removable plug may be provided in the bottom 251 of launch pad 241 as in FIG. 1 if so desired, it being preferred in such cases that the removable tool assistance plug be constructed and shaped for substantially more difficult removal than the plugs 242 so as to prevent undesired removal of the plugs during operation of the launch pad 241.

A female water hose connection is provided in the wall 243 as indicated at 248 for supply of water to and pressurizing of the chamber 245. Annulus wall 253 has an upwardly concavely curved surface 255 in the path of discharge from the orifices 244 and this surface 255 serves to deflect and disperse water from the orifices 244 upwardly.

In operation of the embodiment of FIG. 3, a rocket 211 partially filled with water is connected to launch pad 241 through insertion of bulb connector-seal 247 in the associated rear discharge and connection opening of the rocket body. Water is then added to chamber 245 through a hose (not shown) connected to hose connector 248 sufficient to pressurize the bulb 247 to operational sealing and holding condition, but insufiicient to effect discharge of said plugs 242 from their orifices .244. The rocket 211 is then pressurized through its associated valve 213a, whereupon the water pressure is increased within chamber 245 by remote control from a conventional water faucet supply connection (not shown) to effect discharge of the plugs 242 and resulting spraying of water through the orifices 244. The radial jets of water will be deflected and dispersed upwardly in a generally ring-shaped pattern,

the continuity of which is dependent to a degree upon the number of spacing of orifices 244. With a sufficient quantity and size of orifices in comparison to the available water flow rate into chamber 245, the resulting pressure drop will be sufficient to enable launching of rocket 211. However, launching can be assured by turning the faucet full open to eject the plugs 242 and effect the desired water spray action, and thereupon turning off the faucet, as the pressure in the chamber 245 will in the final condition be reduced to zero, assuring release and lift-off of the rocket 211 from launch pad 241.

In FIGS. 4 and 5 are shown two permissible, though to some degree less advantageous, modifications of first stage sections of a multistage rocket according to the invention. In each instance the stage section incorporates a pressurizable flexible bulb connector-seal 317 for connection of two adjoining first and second stages 311 and 321, the bulb connector-seal 317 being of tear-drop shape for ease of insertion and relatively greater resistance to removal. This facet is considered desirable in various instances for all stage bulb connector-seals, the somewhat less advantageous construction lying in the alternative constructions for connection to the launcher. In FIG. 4 the launcher connection is a flanged nozzle 315f formed on rear wall 315 and having a fluid discharge orifice 3l5b. With this construction the rocket 311 may be launched with the aid of a mechanical slide release launcher such as shown on US. Pat. No. 2,732,657. The discharge orifice 315b in the embodiment of FIG. 5 has a shallow small diameter annular groove 415b formed in the discharge orifice 415b and is adapted to be launched with the aid of a modular stemmed launcher as provided in US. Pat. No. 3,046,694. Various other hybrid stage sections may be employed as desired, though such are generally considered less desirable than the arrangement in which all stages and the launch pad are connected and separated in a similar manner.

A modified bulb connector-seal 517 is shown in the rocket section embodiment 511 of FIGS. 6-8, wherein the bulb wall 517b has a tear-drop shape for relative ease of insertion in comparison to removal of the bulb connector-seal from its complementary female opening, and in which the bulb is longitudinally reinforced while providing collapsibly lateral flexibility of the wall 51712. This is effected by a longitudinal reinforcing rib unit having ribs 517d integrally connecting, or secured to, the tip and root end portions of bulb connector-seal 517 while being in disconnection therefrom in the intermediate enlarged girth flexible annular wall portion 517b.

FIG. 9 shows a further modified form of flexible bulb connector-seal 617 having a generally squat shape with a relatively large diameter securing rim annulus portion 6l7b compared to the depth thereof and a relatively flattened flexible outer end surface 6l7b". The opening in wall 616 of rocket stage section 611 is relatively large so as to enable downwardly and inwardly rolling deflection and release of the retaining rim annulus portion 61712 from its complementary retention groove in response to decrease in pressure in the connecting liquid storage chamber of stage section 611. In this embodiment, as in FIG. 2, the bulb connector-seal 617 is formed separately from the main body of the associated rocket stage section 611, and is bonded thereto along retaining flange 617d and intermediate reduced diameter portion 6170, although in some instances it may be sufficient to bond only along flange 617d, in which latter instance the downwardly and inwardly rolling action of the bulb diaphragm connector-seal 617 may extend over a greater distance during stage separation.

While the invention has been illustrated and described with respect to various illustrative embodiments, various modifications and improvements may be made. For instance, the liquid inserted in any one or more of the missile units and/or launcher unit may be inserted through the pressurizing valve for the particular unit, in lieu of being loaded through the unit discharge orifice or separate launcher fill line or orifice. In addition, in a further modification or improvement, pressurizable flexible wall female inter-unit connectors may be employed in lieu of the illustrated pressurizable male connectors, in which instance the female connector may envelope and releasably engage in peripherally sealing relation a projecting rear section of a next succeeding missile unit or stage, which projecting section may include the discharge orifice section of such next succeeding unit, and thereby effectively closing such discharge orifice of the next succeeding unit during pressurized holding of such unit by the female connector. Also, the spray launcher may be provided with positive orifice-opening-and-missilereleaseefi'ecting means, such as a selectively longitudinally movable common release ring in releasable closure-controlling direct or indirect connection with a plurality of initially closed spray orifices, in lieu of the pressure responsively self-releasable multiple plug spray launcher as illustrated in FIG. 3.
